The preoccupation with existentialist themes, as illustrated by The Rubaiyat of Omar Khayyam from eleventh century Persia, is as old as humanity itself. It becomes more intense whenever there is a cultural crisis, when old values are questioned, when an existing social Weltanschauung is no longer meaningful or valid.
